[asterisk-users] Transfer on RTP timeout?

[Ray Jackson]

Hi all,

We are looking at VoIP over Wifi and I was wondering if anybody had any 
ideas around automatically transfering calls after an RTP timeout?  The 
idea is this: a user is on a call with their IP phone and the connection 
drops (e.g. user walks out of range of their Wifi AP).  Using RTP 
timeout I was hoping rather than just dropping the call I could keep the 
other party on hold whilst transferring the call to another number (i.e. 
a PSTN number).  Essentially, I would like to change the RTP timeout 
logic to lookup a 'forwarding number' in MySQL and then perform a blind 
transfer to that number.  That way the call can stay up rather than the 
user having to redial.  Is there a way of transferring back to the * 
dialplan on RTP timeout to perform some additional steps (instead of 
just hanging up?)

Any suggestions very welcome.

Rgds,
Ray
